Abstract (en)
Three tandem drive units are provided. Outward variable volume working chambers at one end of the drive units are connected via passageways in the piston rods with inward variable volume working chambers at the opposite end of the drive units. In similar fashion, inward variable volume working chambers at the first ends of the drive units are connected to outward variable volume working chambers at the second ends of the drive units, also via passageways in the piston rods. At each end of the assembly, the piston rods pass through piston rod receiving openings in a cylinder head forming member. Each cylinder head forming member includes a manifold passageway and spool valves for controlling a sequencing movement of the drive units. The piston rods provide the spools for the spool valves.
